Saturn Overdrive.

[RedWing]

Thinking of adding a Saturn Overdrive. I would imagine they would add a bit of gear noise. Is it noricble?

Thanks

 

[colojeepguy]

Oh, yeah.

No extra noise for me, I have Warn OD's in 3 jeeps.

 

[Beach66Bum]

That’s the best part!

The overdrive didn't add any addional noise to D18 in my 71.

Same here....the OD is essentially unnoticeable in terms of additional sound....of course, the D18 whine drowns out just about any other potential noise. Maybe the reduced engine rpm from the OD makes the D18 whine more noticeable and that is mistaken for the OD?

To me it lowers the engine noise but adds gear noise, granted mine is a used overdrive and transfercase.

An overdrive doesn't add any gear noise. It can lower engine rpm and noise which may allow you to hear the already present gear noise though.
Next to an 11" brake upgrade, it is probably the best overall upgrade for an old Jeep.

I'm truly astonished by the responses here.

Add me to the "better" crowd.

I'm sure it makes noise but IMHE that's far more than offset by the drop in engine & tranny noise.

Its only as loud as your as your transfercase.

 

[Oldpappy]

I don't notice any "extra noise", Jeeps are noisy machines, and I seldom wear my hearing aids while driving one.

Maybe your overdrive is due for a rebuild?

The gears in an OD are all helical cut so they would make very little noise even if running on their own as long as they have a good oil and good oil level. I have an insulated Hard top on CHUG so its in some ways much quieter then say an open jeep or one with a bikini top so I hear more of the rattles and buzzing sounds and I do get additional buzzing sounds from the OD shifter. I'm working on a way to add something akin to the Transfer case anti rattle springs to my shifter. But the reduction in engine speed so far out classes any other noise that noise should not be part of any concern about installing an OD IMHO

Yup....this is what I think is an OEM (or from dealer) shifter with anti-rattle (and yes, it more of an anti-buzz) clip - ignore the peeling electrical tape - it's pretty much identical to the D18 anti-rattle clips - the shifter has a little machined groove for the clip to sit in

No additional noise here.

Who bought there overdrives new and who is running a used overdrive in a 2nd or 3rd transfercase?

Mine was used.

 

[Fireball]

Mine is a used Warn case but all the bearings and gears were pitted so the guts are all brand new Saturn.

Mine was used.

I bought a used ATV unit from a member here. Unknown supposedly working condition, looked good, installed it and had no issues. No additional noise from mine.
